Magnolia macrophylla - Magnolia à grandes feuilles
Magnolia macrophylla
Magnolia macrophylla
Large-Leaved Cucumber Tree, Great-Leaved Magnolia, Umbrella Tree
Ordered in May 2022, I received it already very beautiful and in excellent condition, about 70/80cm tall, and today it measures around 3m (very vigorous growth, even extremely vigorous, so it matches the description). Its leaves are truly magnificent and hold up quite well against the wind where I live (definitely better than a banana plant, in any case). And I also had the pleasure at the beginning of June of admiring its first flower since it was planted three years ago—it was a huge, spectacular flower about 30cm across. It's really a shame not to be able to include one or two photos because the plant is already stunning at three years old, and it's a plant I absolutely adore.

Description
The Magnolia macrophylla is undoubtedly the most impressive tree of its genus. It is not its flowers that catch the eye at first glance, but its lush leaves, which can exceed 60cm (24in) in length!
Originally from North America, the large-leaved magnolia is a large bush with a rounded habit, reaching 10 to 15 meters in height when fully grown. Its large deciduous oblong foliage, measures from 50 to 80cm (20 to 32in) in length, and is light green on the upper side and whitish gray on the underside.
In summer, beautiful and large fragrant white flowers, 20-25cm (8-10in) in diameter, bloom at the end of the branches. This summer flowering is a characteristic of American species.
Although exotic in appearance, the Magnolia macrophylla is hardy in many regions and can withstand temperatures as low as -15°C (5°F) without damage. It is easy to grow and prefers partial shade, but can tolerate full sun in temperate regions. Avoid windy locations. It prefers light, deep, rich, and moist soil that is neutral to slightly acidic, and does not tolerate heavy soils that retain water in winter.
Plant the Magnolia macrophylla as a standalone specimen or in the back of a border, in an exotic setting with giant Brazilian rhubarb, rodgersias, and hedychiums.

Planting and care
Grow the Magnolia macrophylla preferably in partial shade (in full sun in temperate regions) but not in total shade. Plant it sheltered from cold and dominant winds, in a moist, rich, deep, well-drained neutral or slightly acidic soil. In weakly alkaline soil: dig a very large planting hole of at least 50-60cm (20-24in) deep and add ericaceous compost mixed with your garden soil. Mulch the Magnolia in the first year to prevent it from freezing during heavy winter frosts. Water it in case of drought but in normal conditions watering by rain will be sufficient. From February to June, before leaves appear, remove dead or diseased wood as well as crossing branches.

Hardiness is the lowest winter temperature a plant can endure without suffering serious damage or even dying. However, hardiness is affected by location (a sheltered area, such as a patio), protection (winter cover) and soil type (hardiness is improved by well-drained soil).
